BOTTLE-STOPPER AN D FASTENING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 252,539, dated January 17, 1882. Application filed May 5, 1881. (No model.)

T all whom it may concern:

Be it known that I, GEORGE E. STUART, of

Philadelphia, in the county of Philadelphia stopper fastenings in which the stopper proper,

which is of rubber or elastic material, is attached to a yoke which passes over the mouth of the bottle, and is so connected with the neck wire or band that it maybe drawn down to tighten or release the stopper.

The fasteningof the stoppers mostcom'monl y used are adapted for bottles having one depth of collar, and cannot therefore be readily applied to old bottles having collars of different depths, but must be specially constructed to suit the depth of collar of the bottles for which they are intended. I

The principal object of my invention is to provide stopper-fastenings which shall possess all the advantages of those heretofore made and can be readily applied to old bottles, the collars of which may vary considerably in depth.

The invention consists in the combination, with a bottle-stopper, of a yoke to which the stopper is attached, and which has an eye on one arm and a shoulder formed by a coil at the end of the other arm, and a neck-wire upon which the said eye of the yoke is pivoted, and which is twisted below said eye, and comprises a catch, with which said shoulder upon the yoke may engage. To adapt the fastening for a long or deep collar the neck-wire is twisted more at the eye and the coil upon the yoke is uncoiled, so as to bring the shoulder farther from thetop of the yoke. The yoke also has in its upper part one or more coils, which give it sufficient elasticity to enable it to readily accommodate itself to slight variations in the depth of bottle-collars.

In the accompanyingdrawings, Figurel represents a perspective view of the neck of a bottle having my improved stopper-fastening applied thereto, and Fig. 2 represents a side view and partial section of the stopper and fastening detached from the bottle.

A designates the neck of the bottle to which my stopper-fastening is applied and A designates the collar thereof.

The stopper proper is composed of a metal cap, top, or core, B, and a rubber cushion, B, into which the cap or top B projects, and is secured by vulcanization. As clearly represented in Fig. 2, the upper surface of the cushion B is slightly convex and the under or adjacent surface of the cap or; top Bis flat, so that when the stopper is placed with the shoulder a on the mouth of a bottle and pressure is applied to the top or cap the force will be exerted at the center, and the eifect will be to spread or expand thestopperfrom the center outward.

The yoke O is composed of a piece of bent wire inserted through an eye, I), on the top of the stopper to form a loose attachment therewith. One arm, 0, of the yoke G has an eye, 0, formed at its end, while the other arm, 0 has a shoulder formed by coiling up the end of the wire upon one side, as at d.

D designates the neck-wire, which is inserted through the eye 0 and'twisted, and is then passed round the neck of the bottle and twisted at the ends to secure ittirmly thereon, the twisted ends being bent downward to form a catch, with which the shoulder formed by the coil d may engage when the stopper is to be held down.

In the top part of the yoke O are formed one or more coils, c, which are approximately in line with the two arms 0 O and which give the yoke an amount of elasticity sufficient to compensate for slight variations in the depth of the collars A of different bottles. The coils 0 also give the yoke so much elasticity that when unfastened it will spring sufficiently to carry it into the position shown dotted in Fig. l, and take the stopper entirely away from the mouth of the bottle.

In Fig. 2 I have represented the fastening as usually sold, and adapted to be applied to bottles, even though their collars may be of different depths. After the neck-wire D is passed through the eye 0 it is twisted more or less at f, and is then passed around the neck of the bottle and secured by twisting its ends together.

It will be obvious that if the neck-wire be twisted twice at f the fastening will be adapted for a deeper collar than if twisted once, and

if twisted thiee times it will be adapted for a bottle with a collar of still greater depth. In order to make the arm 0 correspond in length to deeper collars, the coil d may be more or less uncoiled, thus actually lengthening the arm.

As sold, the neck-wires are only twisted once at f, which adapts the fastening for bottles having short collars, and by twisting the neck-- 1. The combination of the stopper B B, the yoke 0, having the eye 0 and coiled end forming the shoulder d, and the neck-wire D, having the twist f, and a catch, with which said shoulder (1 may be engaged, substantially as and for the purpose specified.

2. The combination of the stopper B B, the yoke (J, having the eye 0 and coiled end forming the shoulder d, and also having one or more coils, e, in its upper part, and the neck-wire D, having the twistf, and a catch, with which said shoulder (1 may be engaged, substantially as and for the purpose specified.
